I think so, because passengers have more similar routes. Previously, people could only choose the subway because, first of all, to take the train, you need to look at the timetable, otherwise you can wait a long time, and the subway always runs often. Now trains also run frequently and you don't have to look at the timetable in advance, but just come to the station knowing that you will definitely leave on time. And of course, the comfort of new electric trains plays a role.
Based on all this, the flow of passengers is evenly distributed between the metro and the trains.
Also, the presence of diameters through the center of Moscow plays a role. If the line ends at a train station in Moscow, then passengers simply arrive at the train station and the whole crowd goes to the subway at one/two/ three stations of the same transfer hub, then they go to the line they need and switch to it. But now people can immediately make direct transfers to those lines that they previously could not, and the excess occupancy of other lines is decreasing.
